Hello Harry:
Thanks for your comments, I will try the Carlisle church link, I wasn't aware of it. If 23 years in 1881 she would have been born about 1858 but her birth is not recorded in Civil Register in the years 1855 - 1860 inclusive, all I've checked so far. There is no record of her marriage in the years 1881 - 1893 inclusive.
She shows up as the mother in the birth certificate of my grandfather Albert James Threadwell, born 31 March 1880, 13 Lord Byron St. Her occupation was barmaid, father not listed. Albert Threadwell does not appear in the 1881 census but there is an Albert Twidwell age 1 shown as adopted son living at 23 Lord Byron Terrace (just around the corner); surely this has to be him. I have checked the film record and Twidwell is the name written down but there are no Twidwell births in the Civil Registry. Annie is not at her 1881 address when I check the 1891 census. There are a some Threadwells born in London about the right time (no Annie) and my mother told me it was a "London" name so maybe there is a connection there. Currently, I have the Poor Law books films on order for the St. John's parish in the hope I might find him or her mentioned.
